Die Erfindung wird anhand einer schematischen Zeichnung näher beschrieben.The invention is illustrated by a schematic drawing described.

Die Zeichnung zeigt , abgeschnitten dargestellt, Teile der Einbaustücke 1, 1', eines Walzgerüstes, in denen eine Wechselkassette 2, 2', eingebaut ist. Die Wechselkassette 2, 2', trägt die Zapfen 3, 3', einer Schwinge 4. Ein Anstellantrieb 5 ist an der Wechselkassette 2 gehaltert und arbeitet über ein Getriebe 6 auf den Zapfen 3.The drawing shows, cut off, parts of the chocks 1, 1 ', of a roll stand in which an interchangeable cassette 2, 2 ', is installed. The exchangeable cassette 2, 2 'carries the pins 3, 3 ', a rocker 4. An adjusting drive 5 is on the interchangeable cassette 2 supported and works via a gear 6 on the pin 3rd

In der Schwinge 4 ist eine Führung 7 drehbar gelagert. Auf der Führung 7 ist ein Schleifelement 8, z. B. ein Schleifmop, drehfest, jedoch axial verschiebbar gehaltert. Bei der Führung 7 handelt es sich um eine längsgeschlitzte Hohlwelle 7', die über einen Zahnriemen 9 von einem Drehantrieb 10 antreibbar ist.A guide 7 is rotatably mounted in the rocker 4. On the Guide 7 is a grinding element 8, for. B. a sanding mop, non-rotatable, however, axially slidably supported. The guide 7 is is a longitudinally slotted hollow shaft 7 ', which has a toothed belt 9 can be driven by a rotary drive 10.

In der Hohlwelle 7' ist eine Gewindespindel 11 gelagert. Die Gewindespindel 11 ist über einen Zahnriemen 12 von einem Verschiebeantrieb 13, der an der Schwinge 4 gehaltert ist, drehantreibbar. Auf der Gewindespindel ist eine Kugelumlaufmutter 14 gelagert, die über einen Mitnehmer 15, der die Hohlwelle 7' im Bereich deren nicht gezeigter Schlitze durchdringt, mit dem Schleifelement 8 verbunden ist.A threaded spindle 11 is mounted in the hollow shaft 7 '. The threaded spindle 11 is via a toothed belt 12 from a displacement drive 13, which is held on the rocker 4, can be driven in rotation. On the threaded spindle is a ball nut 14 mounted, which a driver 15, the hollow shaft 7 'in the area thereof shown slots penetrates, connected to the grinding element 8 is.

Die Schleifvorrichtung arbeitet wie folgt:The grinding device works as follows:

Über den Anstellantrieb 5 kann die Schwinge 4 derart verschwenkt werden, daß das Schleifelement 8 gegen die Walze 16 angestellt wird. Über den Drehantrieb 10 wird die Führung 7 und damit das Schleifelement 8 in Drehbewegung versetzt. Gleichzeitig treibt der Verschiebeantrieb 13 die Gewindespindel 11.The swing arm 4 can be pivoted in this way via the adjusting drive 5 be that the grinding element 8 is placed against the roller 16. About the rotary drive 10, the guide 7 and thus the grinding element 8 rotated. At the same time, the sliding drive drives 13 the threaded spindle 11.

Werden die Führung 7 und die Gewindespindel 11 mit gleicher Drehzahl betrieben, so verbleibt das über den Mitnehmer 15 und die Kugelumlaufmutter 14 mit der Gewindespindel 11 in Wirkverbindung stehende Schleifelement in axialer Ruhelage. Sowie der Verschiebeantrieb 13 die Drehzahl der Gewindespindel 11 gegenüber der Drehzahl der Führung 7 erhöht bzw. erniedrigt, verschiebt sich die Kugelumlaufmutter 14 auf der Gewindespindel 11 und verschiebt somit das Schleifelement 8.The guide 7 and the threaded spindle 11 at the same speed operated, it remains on the driver 15 and the ball nut 14 in operative connection with the threaded spindle 11 Grinding element in the axial rest position. As well as the sliding drive 13 the speed of the threaded spindle 11 compared to the speed of the Guide 7 increases or decreases, the ball nut moves 14 on the threaded spindle 11 and thus shifts that Grinding element 8.

Erreicht das Schleifelement eines der Enden der Führung 7, so gelangt es in den Bereich eines der Sensoren 17, 17', die als Schaltnocken ausgebildet sind. Die Sensoren 17, 17' beeinflussen über eine nicht gezeigte Steuerung den Verschiebeantrieb 13 in seiner Drehzahl in Abhängigkeit von der Drehzahl des Drehantriebes 10 so, daß sich das Schleifelement 8 in entgegengesetzter Richtung bewegt.If the grinding element reaches one of the ends of the guide 7, then it reaches the area of one of the sensors 17, 17 ', Switch cams are formed. The sensors 17, 17 'influence via a control, not shown, the displacement drive 13 in its speed depending on the speed of the rotary drive 10 so that the grinding element 8 in the opposite direction emotional.

Für den Fall, daß die Sensoren 17, 17' zu spät oder aus Gründen eines Defekts überhaupt nicht schalten, ist beidseits auf der Gewindespindel 11 ein Bund 19 vorgesehen, gegen den sich die Kugelumlaufmutter 14 anlegt, wodurch eine Beschädigung der Halterung der Gewindespindel 11 und der Hohlwelle 7' vermieden wird. Dabei sorgt weiterhin eine Rutschkupplung 18 dafür, daß die Wirkverbindung vom Drehantrieb 10 über den Zahnriemen 9, die Führung 7, den Mitnehmer 15, die Kugelumlaufmutter 14, die Gewindespindel 11, den Zahnriemen 12 zum Verschiebeantrieb 13 nicht vollkommen starr ist, so daß Beschädigungen der Schleifvorrichtung vermieden werden.In the event that the sensors 17, 17 'too late or for reasons failure to switch at all is on both sides of the Threaded spindle 11 a collar 19 is provided against which the ball nut 14 creates, causing damage to the bracket of Threaded spindle 11 and the hollow shaft 7 'is avoided. Doing so further a slip clutch 18 that the operative connection from Rotary drive 10 via the toothed belt 9, the guide 7, the driver 15, the ball nut 14, the threaded spindle 11, the toothed belt 12 to the sliding drive 13 is not completely rigid, so that Damage to the grinding device can be avoided.
